Yarn Threading Robot Suction Gun Grounding Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Yarn threading robots experience static electricity buildup due to contact with yarns, which can adversely affect their control systems, leading to potential malfunctions and inefficiencies in yarn processing operations.
Innovation Solution
A conductive path is established from the retaining portion of the robot to a ground terminal, ensuring that static electricity is dissipated without flowing to the controller, using insulated wires and separate grounding paths to prevent interference and maintain system stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the retaining portion makes contact with yarns to perform yarn threading operations, then the productivity and automation level are improved, but static electricity accumulates in the retaining portion which may adversely affect the control system
Solution Approach 1:
The grounding path is segmented into two separate paths: one for the controller and one for the retaining portion. This segmentation ensures that static electricity from the retaining portion does not flow through the controller, eliminating electrical interference while maintaining automation functionality.
Solution Approach 2:
A dedicated grounding terminal and grounding wire act as an intermediary path for static electricity discharge. This intermediary grounding system provides a safe discharge route for static charges without involving the controller, thus protecting the control system from electrical damage.
2Reliability
If a grounding path is provided from the retaining portion to the controller, then static electricity can be discharged, but the controller may be adversely influenced by electric charges
Solution Approach 1:
The grounding system is divided into separate paths: one path through the grounding terminal for the retaining portion, and another path through the grounding wire for the controller. This segmentation allows both components to be grounded independently, preventing static electricity from damaging the controller while maintaining system reliability.
3Adaptability or versatility
If the robot arm moves freely to thread yarns to various positions, then the adaptability and operation flexibility are improved, but the complexity of managing conductive paths and insulation increases
Solution Approach 1:
The grounding terminal serves as a fixed intermediary point that remains stationary regardless of robot arm movement. The grounding wire connects this fixed terminal to the moving retaining portion, allowing the robot to move freely while maintaining a reliable grounding connection through the flexible wire.
Solution Approach 2:
The grounding terminal provides multiple functions: it serves as a grounding point for the retaining portion, a reference point for the grounding wire, and a stable electrical connection point that remains effective regardless of robot position or orientation.

AI summary
Static electricity generated in a retaining portion is swiftly removed and an influence of the static electricity on a controller is restrained. A yarn threading robot 3 performing yarn threading to a take-up apparatus 2 includes a robot main body 31, a robotic arm 32 connected to the robot main body 31, a suction gun 37 attached to the robotic arm 32 to retain yarns, a robot controller 102, and a terminal 55d in contact with a grounded ground wire 54. A conductive path 60 is formed to extend from the suction gun 37 to the terminal 55d without passing the robot controller 102 so as to cause the suction gun 37 to be electrically conductive with the terminal 55d. The suction gun 37 is connected to the ground wire 54 via the conductive path 60 and the terminal 55d so as to be grounded. On this account, the static electricity generated in the suction gun 37 due to contact with the yarn Y is swiftly removed and the occurrence of adverse effects due to the flow of electric changes to the robot controller 102 is restrained.
